' BEDSTEAD-SECURING DEVICE.

SPECIFICATION forming part of Letters Patent No. 574,717, dated-January 5, 1897.

Application filed November 16, 1895. Serial No. 569,165. (No model.)

To (oil whom, it may calmer/t.-

Be it known that 1", MILTON L. Gnoss, a citizen of the United States, and a resident of the city of Philadelphia and State of Penn- 5 sylvania, have invented a certain new and useful Improvement in Bedstead-Securing Devices; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification.

My invention has for its object to provide a readily assembled and detachable device for rigidly securing the parts of the bedsteadframe together, so as to prevent any rattling or movement of the parts of the joint upon each other when in position; and it consists in the device hereinafter particularly described and claimed. 7 In the accompanying; drawings, Figure l is a perspective view illustrating my invention, showing a joint of a bed-frame with the parts assembled and in position. Fig. 2 is a side elevation and partially sectional view of the same. Fig. 3 is an enlarged detail view of the securing device.

A represents the vertical post of the head or foot of a metallic bedstead-frame, to which my invention is principally adapted, though it is also applicable to bedstead-frames of other material. A is the outer longitudinally-disposed bed-supporting bar.

In the drawings, the post A is represented as of tubular construction, and the bar A as 3 5 angular, though their shapes are not material and may vary according to the character of the bedstead-frame to which my invention may be applied.

To the bar A is secured a vertically-disposed plate B, and to the plate B is rigidly secured, by riveting or otherwise, the vertically-disposed short bar or plate 0, having an inner face 0 of a shape or contour adapted to the shape of the face of the post A, against 5 which it is intended to impinge.

A represents one of the end cross-bars, adapted to support the mattress, having its opposite ends resting upon and supported by the longitudinal bar A.

In the plate 0, I provide an orifice 0, extending through thesaid plate, having an enlarged lower mouth or opening 0, with the upper walls to of the orifice O inclined and converging at the top of the orifice, forming a wedge-shaped recess. I also provide upon the outer face of the plate 0, around the edges of the opening or recess, a wedge shaped shoulder f, inclining at its minimum thickness around the portion 0 to its greatest thickness at or above the point of convergence of the walls to of the orifice O.

In the post A, I provide rigidly a pin a, adapted to protrude through the orifice O of the plate 0, having upon its protruding end a shouldered head a. As shown in the draW- ings, the pin Ct is preferably riveted in the post A. The construction is such that when it is desired to assemble the parts the plate 0 is so positioned that the protruding end of the pin a, with its head a, is intruded through the mouth 0 of the, orifice O. The plate 0 and parts attached thereto are then allowed to settle, or are forced down, as to the position shown in Fig. 1, so that the inner wedgeshaped walls to of the opening 0 grip and bind firmly upon the neck of the protruding portion of the pin a. At the same time the outer face of the wedge-shaped shoulder f impinges against the inner face of the head a. Thus the farther the plate 0 is forced down the tighter will the inner face of the plate 0 be bound against the impinging surfaces of the walls of the post A.

In the drawings I have illustrated two of the securing devices provided upon the joint. 8 5 Any desired number, however, may be employed.

It is clear that in the construction of my invention the possibility of a loose or rat- I tling joint is prevented, and that all longitudinal, lateral, or other movement of the parts are overcome, as a positive firm joint must result when properly constructed. It is also clear that in the construction of my invention the bedstead-frame may be assembled or taken apart without difficulty in a minimum space of time withoutinjury to the parts and without the use of tools.

Having thus described my invention, what I claim, and desire to secure by Letters Pat- I00 ent, iso 1. In a bedstead-frame a round metal post,

A, plate, 0, having a eoncaved face, 0, adapted to the convexed walls of the post, A, a protruding headed pin, a, secured in the post, A, orifice, O, in plate, C, having enlarged mouth, 0, and inclined or converging Wedge-shaped Walls, 20, Wedge-shaped shoulcler, f, provided upon the outer face of the plate, 0, around the edges of-the inclined walls, w, having its greatest thickness at or near the point of convergence diminishing to a minimum at or near the mouth portion, 0, substantially as described.

2. The combination in a securing device for metallic bedstead, of the vertical tube A, headed pins a, secured in the tube and projecting slightly therefrom, a side rail A, a vertically-disposed plate B, secured to said rail, a bar or plate C, secured to or formed integral with the plate B, and having a con- MILTON L.
